In which of the following modes of data transmission, can the data flow in both directions but in only one direction at a time?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Half-duplex.
Half-Duplex is a data transmission mode where communication can occur in both directions, but only one direction at a time. It allows alternating transmission and reception of data, making it suitable for devices like walkie-talkies or CB radios. This contrasts with Simplex (one-way) and Full-Duplex (simultaneous two-way) communication.
